Save and restore SRIOV-related config registers.

Save the value of the IOV control and page size registers and restore
them (along with the VF count) in pci_cfg_save/pci_cfg_restore.  This
ensures ARI remains enabled if a PF driver resets itself during the
PCI_IOV_INIT callback.  This might also properly restore SRIOV state
across suspend/resume.
